I don't know what started my interest, but the idea of sex with an animal always fascinated me. I just didn't know what to look for until one fateful morning on a bus trip I overheard someone talking about a bestiality website. Hearing that term and seeing that site for the first time sealed the deal and opened the flood gates.
I didn't get to act until many many years later. I had a (nonzoo) friend I had confided in about it and she was both accepting and encouraging. About a year after that, I rescued a two(ish) year old German Shepherd from the side of the road.
Over the next number of months, I had her checked over by a vet, vaccinated, named, chipped, and back in good health. She was happy, enjoyed obliterating any squeaky toy in record time, and chasing reflections or light.
I had learned from the vet she was not yet spayed, so the topic of whether or not anything would happen between me and the dog came up a few times with my friend. I don't remember how it came about, but my friend ultimately offered a bottle of lube for use she had as I didn't have any at the time.
After making sure it was a safe kind for the dog, I remember nervously driving to her place, her handing me the bottle while knowing full well what I would use it for, me thanking her, and then driving back home.
By that evening, after careful exploration and patience, my dog was receptive and she became my first, and so far only, dog. We had many wonderful experiences together, especially as I got to know what she likes.
To this day my friend says she contributes to my delinquency. She and I have also had a few zoo experiences together, and plan on more.
My dog has since been spayed due to a cancer scare and is getting up there in age. I like to say she's retired. But she's still alive and happy despite the issues her age is bringing on.
She's currently sleeping on the floor with her favorite squeaky ball.
